J Am Coll Cardiol:辅助性治疗高甘油三酯血症:尚未满足的需求

尽管二级和一级预防中,高强度他汀在降低动脉粥样硬化性心血管疾病事件中具有重要作用,但持续存在大量的残余风险,尤其在2型糖尿病、代谢综合征和肥胖高风险患者中。发表在《J Am Coll Cardiol》的一项研究表明,在这些高风险患者中,强化降低LDL-C远远不够!

尽管二级和一级预防中,高强度他汀在降低动脉粥样硬化性血管疾病事件中具有重要作用,但持续存在大量的残余风险,尤其在2型糖尿病代谢综合征和肥胖高风险患者中。发表在《J Am Coll Cardiol》的一项研究表明,在这些高风险患者中,强化降低LDL-C远远不够!

目前,甘油三酯(TGs)和非高密度脂蛋白胆固醇水平的升高,作为残余动脉粥样硬化性血管疾病风险的重要介质的作用,被广泛关注,也得到了遗传连锁研究的进一步支持。

既往贝特类、烟酸和大多数胆固醇酯转移蛋白抑制剂(旨在针对高密度脂蛋白胆固醇的升高和/或TG的降低)的试验,未能表现出确凿的证据,即他汀最佳控制了低密度脂蛋白胆固醇水平后,事件增量减少。

虽然ω-3脂肪酸在降低TG水平上是有效的,并且具有多效性效应,如降低斑块不稳定性和动脉粥样硬化的促炎介质,但目前缺乏临床结局数据。在分子水平上,越来越多的证据表明,与DHA相比,EPA对动脉炎症产生更有利的影响。目前,在他汀类药物治疗的ASCVD患者或高风险糖尿病患者中,高剂量(4 g)EPA的长期临床试验即将完成,另一项EPA + DHA试验可能在2019年至2020年结束。
